Replaceable rubber track pulley is a new technology developed in the mid-90s of the 20th century abroad, and a large number of scientific research and technical personnel at home and abroad are engaged in the design, simulation, test and other development of track pulleys. At present, the more famous companies that develop replaceable rubber track wheels abroad include MATTRACKS, SOUCY TRACK and other companies. The track conversion system of MATTRACKS can be equipped with most four-wheel drive vehicles up to 9,525kg, reaching speeds of up to 64km/h on hard roads.

And there is a very low ground bed strength, only 0· 105。 Their products have been formed into a variety of models, multiple series for customers to choose from. Domestic research on track wheels is also increasing, Liwei company has developed a series of track wheel products for ATVs and light vehicles; Chongqing Nedshan Hua Special Vehicle Co., Ltd. has also carried out a systematic investigation and research on the structure of the track wheel, and has trial-produced a series of products and achieved good results.

Due to the various advantages of replaceable V-track wheels, its application in daily life has been very extensive, mainly used in the following aspects:

(1) Law enforcement, search and rescue, etc. Replaceable triangular track wheels are widely used in law enforcement, firefighting, rescue and medical emergency services, mainly used for rapid maneuvering of personnel and equipment under harsh driving conditions and special conditions to meet the off-road and obstacle crossing performance requirements of special weapons and equipment. It has absolute superiority in conquering extreme climatic conditions, remote areas and complex terrain. It is usually installed in personnel transport vehicles, command vehicles and rescue vehicles for special area operations.

 (2) Agricultural tracks applications. The emergence of replaceable triangular track wheels solves the problems of subsidence, slippage and inefficiency encountered by traditional wheeled agricultural machinery in loose sand, rice fields and wet and soft ground, and the crawler system can provide greater ground contact, effectively disperse the self-weight of agricultural machinery, reduce ground pressure, and reduce damage to soil. At present, it is mainly used for crawler wheeled tractors, harvesters, seeders, trucks and forklifts.

(3) Commercial applications. Replaceable track units are mainly used in the commercial entertainment industry for beach cleanups, tours or tour guides, park services, environmental protection, golf course maintenance and wilderness lighting. The tour company installs replaceable track units on (snowmobiles tracks) to transport visitors safely and comfortably to the wilderness. Vehicles equipped with replaceable track units are also used to repair road tracks.
